A sprinkler has an upwardly facing sprinkler bowl at the top of the sprinkler body in which water can collect during operation of the sprinkler when the riser of the sprinkler is popped up. At least one nozzle on the sprinkler comprises a siphon nozzle that has a siphon tube extending downwardly into the bowl when the riser is popped up and the sprinkler is operating. The siphon effect created in the siphon nozzle siphons water from the bowl and through the tube to eject the water in the bowl along with the main water flow through the nozzle. The siphon tube is flexible to collapse or bend within the bowl when the riser retracts.
